This clock representation shows some of the major units of geological time and definitive events of Earth history.

The geology or deep time of Earth's past has been organized into various units according to events which took place.

► Analyses shoreline altitude data using Ordinary Kriging and Gaussian Trend Surface Analysis.

► Depicts an elliptical pattern of RSL change around a centre in the South East Grampians.

The patterns for the most widely occurring shorelines were analysed and found to be similar and common centre and axis models were developed for all shorelines.

The analyses described provide models of the spatial pattern of Holocene RSL change in the area between ca 8100 cal. BP based on 2262 high resolution shoreline altitude measurements.
